cnN-noDY MACHINE;

Be it'known that I, FRANK RUDOLPHI, a

' citizen of the United sans, residing in chicago, in the county of Cookand State of Illinois, have invented a new and useful Improvement inCan-Body Machines, ofA

which the follo'win is a specification.

cheaply andperfectly manufactur can oodies Y amount of solder un Myinvention etes to improvements in can body makin machines, and morepartcularly-to maclgiines for making lock side seam can bodies.

' f The object of my invention is to provide an automatic lock side seamcan bod making machine of a.' simple, eiiicient an durable constructionby means of which can bodies may be automatically, rapidi an?l reducedof uniform size or diameter, un by means ofwhich the soldered sido seamsmay be made uniformly perfectand hermetically tiht with a minimumwithout smearing or coating either the interior or exterior surface ofthe can body with solder adjacent to the sideseam.

In manufacturing or producinv' from flat rectangular can body lonkssheet metal .cans of uniform size or diameter, having lock side seams,with the solder properly lsweated through or between the several foldsof the lock' seam, it-` is necessa that a num 'oer of Jsuccessiveoperations e performed upon Vthe can body blank, such as feeding thesame one by one from a stack or pile of blanks-the carrying or moving ofthe blank through the machine to the several operating devices, formingoppositely turned hooks or edge folds on the opposite ends of the blank,roperl'y guiding or presenting the blank to t e edging, folding orhook'forming devicesrand properly clamping it dur- ;ing the edge foldingor hook forming operation, sov that the hooks or edge folds may beformed of'proper width and in proper relation to the blank, the formingof the blank into the cylindrical or other shape of the/can body the proer interlocking or drawing,rr together of the looks or edge folds,the:bumpingorl closing: of the seam. the propos xppingof the blank on.thev body former horn prepartorytothofformingor folding ofthe around'the' hom,'the

The can body blanks X are automatically fed one by one from the pile orstack of blanks X1 in the blank holder BL of the feeder B and deliveredthereby to the blank conveyer D.'

The blank feeder B referably has a shoulder b which projects rom theinner face of the feeder about the thickness of one of the blanks X soas to engage the lower-most blank only of the pile and shift or slip itupward into the slot b1 of the feeder safeguard device or separator B'-land thus disengage the blank from the lip ZF of the blank holder B1. Thefeeder has two movements, one a sliding or reci rocating movement toslip the disengage blank urto the slot b1 of these arator B2 `anddisengage the lower edge-o the blank from the lip L of the holder B1 andthe other movement being a swinging or lateral one tov permit the blankto drop down upon the blank conveyer D. To' provide for this doublemovement of the feeder B, it is mounted to slide in a pivoted orswinging guide B73.

The guides C C for supporting the blanks and guiding the sarneas theyare moved forwaru by the blank conveyer D so as to present the blank inproper relation to the book former-s or edge folders E, preferablyconsist of angle bars secured to the sta'- tionaify frame of the.machine.

Cl C* are intermediate guides tofproperly ,support themiddle portion ofthe blank.

Y l The blank conveyer Dpreferably consists ,of a' pairgfreciproeatingjbarsnr slides re- -ose, 1ao vx3 f eiprocating in suitableguides or Ways D2 on the frame of the machine, furnished with a series,`of pairs of fingers or pawls J, each having a spring d and which lingeisor 5 pan-ls engage the'blank and push it for ard.

The blank conveyer bars or slides advance the can bodies forward by astep by `step i movement iirst to -the hook formers` E. then to imvintermediate station or space between the hook formers and the bodyformer horn (i and then to the body former horn. and then theean bodyejector D pushes the can v body oli the body former horn onto theIsoldering horn along which it is then ad yanced by a step by stepmovement b r the carrier drizonreyer R of the soldering meehanisrrn Theejector' D is preferably connected to the blank eonveyer D and operatedtherefrom.

opposite ends of the blank- X. The lower clamp El (1f-each pair `ismounted on the stationary frame of the machine and the upper clamp-ofeach pair is the movable member and opened from and closed against thelower member to admit the blank between them and to clam the same. One

' clamp of each air E E 1S provided with a hook forming ip e2 over whichthe hook or edge fold .if or .1 -1, as. the case may be. is .35 foi-medor bent, the hook forming lip e2 be* ing on the upper clamp E to fornithe npturned hook ai, and on the, lower clamp -E atthe opposite end toform the downtnrned hook or edge fold The upper clan1ps i 40 E E arepreferably secured to movable bars E having arms E* hinged at E to theframe of the machine. The intermediate clamlrl'lz is preierablyv pressedyieldingly against the middle portion of the biank by a spring csurrounding a pin e1 by which the movable clamp is' connected with the.movable eros` bar il. The upper segments ll ll are preferabll,Y forceddown to irmly clamp the blank between the upper clamps l E' and lowerclamps El El by means of t'ne cross bar E which is furnished with ad-]'uetable screws or pins Ei to engage the movable bar-3 E3 to which theupper clamps` l-l are secured. The upper or nim able clamps li restnormally with their own weight and with that of their holder bars E onthe blanks AX as they are fed or conveyed fori ward beneath the same byihe bla-nk conrever l) and in connection with the middle clamp E2 serrenot onlyv to straiglhien.Av Smooth and-Hatten thefblai-lks. but also topireyent danger o the blanks being overcarried bjr'- the conveytrl') inits quick or rapitiy reciprocating movement. tlnfr insur- 55ingthdftblanks beingv always properly pre- 'l sented to the hook foldersor edge formers l l" l-`.

liaeh of the two rotar)v or rocking book formers or edget'olders l" issecured to a rockingl holder l1" b v or through which the necefesarv orrocking movement, is imparted to it. The two` rocking hook fox-mers I"are alike and are reversely mounted or disposed so that. one willt'orm'an upturned hook and the other a downturned hook. Each of thesehook formery l" furnished with a longitudinal recess or groove f toreceive the projecting end of the blank X and serve as a guide thereforin adjusting the position of the blank between the. two hook forniers FF. Each of the hook fm'mersl" is also provided with a projectingshoulder or bead f1 which engages. the projeetingnr end of the biank andbends itat right angles to the plane of the blank when the hook former.is rocked in one direction and also with a further shoulder or bead fand projecting lip f which serve when the hook former is rocked in theopposite direction to complete the formation of the hook w or .r1 :isthe case may be fron: the formingr lip 12 of the. clamp D or Dl as the.caso may be. After the format-ion of the hook is thus cfunploted, thehook former l" returns to its central or normal position ready toreceive the next blank. he body formenhorn G is expansiole andcollapsible or provided with movable 'segments or wings y, preferablyhinged to the main portion of the horn by pivot projections g The hornis thus adapted to Collapse while, the can body blank X is wrappedaround tbe horn, and the edge folds or hooks J.- .el thereof farriedpast each other` so that they may interlock or draw together. and alsoadapted to expand to draw the hooks .r .1," snugly together preparalor)vto the humping or elosinpr of the seal and also to again collapse orcontract to enable the body to be readily extracted or pushed ott thehorn. The .horn (i has at its lower part a groove y to receive the. lockseam so that the seam will project on the in side oi the can bod;v andleave the exterior surface of the can body smooth at the lock seam.- Thehorn (nl has at its upper part a guide groove g" to receive thereciprocating i can bod) extractor D by which the can l body is pushed,ot lthe body foriuer horn leo nto the soldering horn. The wings or seg-Vments of the. horn are thus expanded or v engage wedge blocks g" onarms gl hinged to the horn atg and which bear against adjusting screws yon the movable Wings or segments g' of the horn. The horn G is supportedfrom the upright web or plate A1 of the frame by a longitudinal bolt yextending through a hole g in the. horn.
